Invited (In person)

Over the last two years, a revamped Miniball has been conducting physics experiments across the nuclear chart. Comprising eight assemblies of three electronically-segmented high-purity germanium crystals, the spectrometer measures gamma-rays emitted from fast-moving nuclei following various nuclear reactions. As well as being refurbished with new endcaps, cryostats, and AGATA-like...

We present recent online results obtained in the IS595 experiment performed in October 2023. Aim of this work is the investigation of excited states in ${}^{133,134}$Sb and, possibly, ${}^{134,135}$Te, by employing a cluster transfer reaction of a ${}^{132}$Sn beam (at 3.9 MeV/A) on a ${}^7$LiF target (1.5 mg/cm${}^2$ thick). The experiment ran for 7 days very smoothly, with a very pure and stable...

73. The first TDRIV g-factor measurement on a radioactive ion beam: ${}^{28}$Mg

The Island of Inversion in the neutron-rich $N=20$ region arises in part due to a significant reduction in the energy gap between the sd and fp shells. Recent theoretical calculations [1] and experimental results in ${}^{30}$Mg [2] favor a much smoother transition towards the Island of Inversion than previously thought, with considerable fp admixtures in the ground state of ${}^{30}$Mg and small...

53. Combined conversion electron and gamma-ray spectroscopy of neutron-deficient Hg isotopes utilising the SPEDE spectrometer

The shape coexistence phenomenon close to the midshell N=104 in the lead region has been under study for several decades. The E0 transitions can be used to study this phenomenon. These transitions can be detected mainly through internal conversion in this region. To investigate this phenomenon, the combined conversion electron and gamma-ray spectroscopy experiments IS563 and IS699 were...

77. Scattering Studies at the SEC (XT03) beamline at HIE-ISOLDE

Maria Jose Garcia Borge (Consejo Superior de Investigaciones Cientificas (CSIC) (ES))

Invited (In person)

The SEC (Scattering Experiments Chamber) at the XT03 Beamline of HIE-ISOLDE is an experimental station to facilitate diversified reaction experiments. The chamber is sufficiently big to accumulate a variety of charge particle detectors as well as scintillator detectors for gamma detection. It is equipped with a rotational disc of 50 cm radius radially graduated and supplied with Al-bars for...
